One of the main interest of physical models is to offer great control possibilities. Real time execution of our model on a desktop workstation (SGI Indy) renders control possibilities even more interesting. Mouse and graphic sliders are useful and convenient for research, but combining the evolution of several parameters simultaneously is necessary for musical use and interpretation, as done naturally by the trumpet player. Moreover, the possibilities and limits of the instrument are determined all the better as the musician can freely explore the parameter space. For musical control, we have written a MIDI interface connected to an electronic keyboard, a breath controller, and a foot pedal. The instrument and its real-time control will be demonstrated at the conference.
